Recreating QGuiApplication is not a common case, ever.
Plus no one said the QPixmap cache would be shared across QGuiApplication
instances. I don't think that was the intention. In fact that could be used
to access some data of another "run" meant to be destroyed/erased/forgotten.
Using QThreadSto

A very simple solution is to make the cache a member of QGA(P), create
it lazily if needed (like Q_G_S does; but I've got the funny feeling
that the pixmap cache is used in 100% Qt apps, so maybe that's not even
needed), and kill it
